Hey, thanks for everyone's replies and sharing of similar issues! TLDR: I re-imported the clip and auto-transcribed and it worked. Maybe that will work for you too. And maybe it had something to do with needed to clear the cache, because no matter how many times I've tried hitting re-transcribe on the first instance of the clip in my project, it would not separate the speakers.
More details:
- I'm transcribing a clip, not a sequence. BUT, I had first tried putting only that clip into a sequence
